## Issue

I have a **Type Error** from **centered average** algorithm in Python. this is my code

```
def calc_centered_average(numbers):
sorted_list = sorted(numbers)
return sum(sorted_list[1:-1])/(len(numbers)-2)
# return subnumbers, centered_average
numbers = [1, 4, 5, 6, 100]
sublist, cavg = calc_centered_average(numbers)
print(f"The centered average of {numbers} is {cavg} (based on {sublist}).")
```

## Solution

Your problem is caused because you are returning one value instead of two in your function. Here is the correct way that I assume you should do it:

```
def calc_centered_average(numbers):
sorted_list = sorted(numbers)
subnumbers = sorted_list[1:-1]
centered_average = sum(subnumbers)/(len(numbers)-2)
return subnumbers, centered_average
numbers = [1, 4, 5, 6, 100]
sublist, cavg = calc_centered_average(numbers)
print(f"The centered average of {numbers} is {cavg} (based on {sublist}).")
```
